Hi. Can someone please show me how to do the following problem?
"A 5620 kg open railroad car coasts along with a constant speed of 8.66 m/s on a level track. Snow begins to fall vertically and fills the car at a rate of 3.50 kg per minute. Ignoring friction with the tracks, what is the speed of the car after 86.4 minutes?"

This problem can be solved using the basic principle of Conservation of Linear Momentum.
<br>Momentum(p) is defined as p= Mass(M)*Velocity(v). And, according to Newton's Laws in any system when there is no net force acting on the system, the Momentum is conserved.
<br>In our case : the railroad car has some initial ...
Conservation of Linear Momentum is applied. The constant speed of functions are given.
